Abstract

We present in this paper the concept of solar hybrid road and focus on the thermal performances of such system. Main differences between these multi-layer structures with traditional road structures come from the pavement surface, which can be opaque or semi-transparent and the porous sub-layer, submitted to fluid flow. These structures aim at collecting solar energy during the summer season, what helps also to prevent from a too high temperature and urban heat island effect. A finite element model is presented to couple thermal diffusion, hydraulic convection and radiative transfer. This numerical model allows to compute the temperature field under different weather conditions and also to evaluate the thermal performances of such system. Annual simulations are performed and a comparison between two surface layer solutions for different locations and climates is presented and discussed.
